目前,汽车贴膜就是在车辆前后风挡玻璃、侧窗玻璃以及天窗上贴上一层薄膜状物体,主要作用是阻挡紫外线、阻隔部分热量以及防止玻璃突然爆裂导致伤人等情况发生,同时根据太阳膜的单向透视性能,达到保护个人隐私的目的。但是这种贴膜只能一次性使用,而且为了应对汽车在行驶过程中遇到的各种状况,人们就会相应地对车窗有各种不同的需求。目前一次性车窗贴膜并没有很好地满足人们对车窗各种不同的需求。文中设计一种简单的汽车贴膜升降切换系统,可以根据人们的不同需求,随时随地切换不同功能的贴膜。
Currently, the car is the film in the car windshield glass, side windows and sunroof affixed to a thin film-like objects, the main role is to block the UV, block part of the heat and prevent sudden burst of glass leading to wounding, etc., at the same time according to the sun film One-way perspective performance, to protect the privacy of individuals. But this foil can only be used once, and in response to the various conditions encountered in the car during driving, people will accordingly have different needs of the windows. Currently a one-time car window film does not well meet people’s different needs of the windows. The article designed a simple car foil lift switching system, according to the different needs of people, switching film with different functions at any time.
